Routine Description:
This function get the DRIVER_INFO_1 Pointer from a hPrinter
Arguments:
hPrinter - The handle to the printer interested
DrvInfoLevel - if 1 then DRIVER_INFO_1 is returned else if 2 then DRIVER_INFO_2 is returned, any other vaules are invlaid
Return Value:
the return value is NULL if failed else a pointer to the DRIVER_INFO_1 or DRIVER_INFO_2 is returned, the caller must call LocalFree() to free the memory object after using it.
